22 minute charge time with the air cooled Makstar Optimum Charging System. Lithium-ion batteries have greater life spans than their Ni-MH or Ni-Cad counterparts giving 430% greater run time. Lithium-ion's 40% weight saving means 18 volt power can be obtained by a battery that weighs the same as a 12 volt Ni-MH battery.

Battery type Lithium-ion Ni-Cad (Nickel Cadmium) batteries are reasonably priced but are very damaging to the environment. They also need to be completely discharged and cool to be able to accept a full charge. With Ni-MH (Nickel Metal Hydride) battery technology it was possible to increased the amperage to 3.0Ah, they are also a better option environmentally than Ni-Cad. They can be fully charged whether they are warm or partially discharged. Li-ion or Lithium-ion batteries are lighter weight, quicker charging and with more run time than an equal voltage Ni-Cad or Ni-MH battery. These batteries have a chip that communicates with the charger for optimum charging. Lithium-ion batteries also offer much improved charge retention over long periods of storage. Li-ion batteries do not have to be fully discharged before charging in fact they can be charged at any time with no ill effect.

Battery Voltage 18V The voltage of a battery gives power to the machine. An 18V tool is more powerful than a 14.4V or a 7.2V. Note: this only applies to machines in the same series. Amperage The easiest way to describe the amperage of a battery is to relate it to the size of the petrol tank in your car. A 3.0Ah battery has a bigger tank and can therefore work for longer than a 1.3Ah battery of the same voltage.
